Tropical Storm Isaias Forecast to Spread Northward Along the East Coast, Bringing Storm Surge, Heavy Rainfall, and Flash Floods


According to the National Oceanic and Atmospheric Association (NOAA) National Hurricane Center (NHC), Tropical Storm Isaias was located 55 miles southeast of Fort Pierce and 120 miles south-southeast of Cape Canaveral, with tropical-storm-force winds extending out 115 miles from the eye of the storm. Isaias is  expected to move slowly northward along the east coast of Florida through early Monday, gathering strength in the warm gulf waters. The NHC warns that a dangerous storm surge of two to four feet is possible along waterways on the east coast of Florida from Jupiter Inlet to Ponte Vedra Beach. Tropical Storm Isaias is expected to continue moving along the southeast coast of the mainland United States (US) throughout the week, potentially making landfall in the Carolinas.

Eastern Florida could experience tropical storm conditions throughout Sunday evening, with winds from 39 to 73 mph, and the tropical storm conditions are expected to reach coastal Georgia and the Carolinas on Monday and Tuesday.

The Federal Emergency Management Agency (FEMA) encourages individuals to take the necessary precautions and prepare for flash flooding. Flash floods can develop with little to no warning, quickly changing the surrounding area. FEMA suggested individuals seek higher ground, avoid walking or driving in flood waters, and  heed the warnings of local authorities.
